This invention relates to improvements in electric batteries of the drycell type, and relates more particularly to the means of providing atight joint between the inner wall of the outer casing and the materialWith which the. open end of the outer easing is to be closed, andrelates still more particularly to improvements in electric batteries ofthe class described in the United States Patent No. 1, the 13th day ofJan The invention 0 tion, combination vices hereinafter s 328,027,issued to me nary, 1920. onsists in the construcand arrangement ofdehown and described. The accompanying drawing is an eleva-' tion,partly in vertical central section, of a dry battery constructed-andarranged in accordance with m invention.

As described in the specification of my previous United States PatentNo. 1,328,027, the outer casing 1 contains the mixture 20f carbon andhydrogen absorbingmaterial, such for instance, as a mixture of graphiteand manganese peroxide. The lining 3 is of material which is adapted toabsorb liquid has to be formed vided with and in which the sa inpresence of'tWo witnesses.

and the negative black mixture 2.

The outer casing 1 whose open end is to be closed with a seal 5 ofisuitable material, preferably asphalt, is internally provided with acircumferential flange 6 adapted to engage corresponding groove whichnaturally 40 in the asphalt seal when over the open end of the rtheupper face of the actually enveloping the pole 4 is placed within thethe same is placed outer casing. Ove said flange 6 and outer and innerwal of the outer casing I place a suitable insulatlng water proof paperor fabric 7 so that a tlght joint is formed between the seal and thecontainer wall.
